MACHINE FOR REPAIRING PIGKER-APRONS.

Specification of Letters Patent.

Application filed September 20, 1909.

Patented June 13, 1911. Serial No. 518,639.

To all whom it may concern:

Be it known that I, NEWTON VVILLIAMs, a citizen of the United States,residing at Fall River, in the county of Bristol and State ofMassachusetts, have invented a new and useful Machine for RepairingPicker- Aprons, of which the following is a specification.

The present invention has reference to improvements in machines forrepairing picker aprons. These aprons, as is generally understood,consist ordinarily of a canvas belt spanning a pair of spaced leatherbelts and arranged upon the upper faces of the same, the canvas beltbeing in turn provided at intervals with spiked battens. During use, itfrequently happens that these battens become broken or otherwiseinjured, and hence must be removed, and new ones substituted. Thedetachment of the battens under such circumstances is, however, a matterof extreme difliculty, owing both to the very considerable weight of thebelt and to the fact that rivets are employed for securing the battensto the belt, it being necessary to cut off the tops of the rivets inorder to remove the battens.

It is the object of my invention, therefore, to produce, a machinewhereby the repairing of the belts will be materially facilitated.

A structural embodiment of the invention is illustrated in theaccompanying drawings, wherein:

Figure l is a plan View of the improved machine, Fig. 2 is a sideelevation thereof, Figs. 3 and 4 are end elevations of the same, Fig. 5is an enlarged detail View of the movable foot and its associatedadjusting devices.

In said drawings, a and A indicate the two upright legs which aremounted on a suitable base A and support upon their upper ends the tableB, the leg A being rigidly secured to said base. Said table issubstantially rectangular in shape, and its floor is formed with asimilar opening 7) into which the panel H, hereinafter referred to, isarranged to move. At opposite sides of the *table are arranged thelongitudinal shafts D and (Z provided, respectively, with pulleys c andC connected by a belt 0', the pulley 0 having a crank handle 0 attachedthereto. Intermediate their ends, the shafts D and (Z are studded withspikes as indicated by the characters (Z and (Z, the spikes beingdesigned to engage the picker belt, (not shown), and advance or retractthe same according to the direction in which said shafts are rotated.There is also connected to the table a pair of adjustable transverseguides E and 6 arranged in spaced parallel relation, the fastening bolts6 and e of said guides being slidable in the slots f and F formed in thetable floor. The above-mentioned panel H is likewise rectangular, andits dimensions are appreciably smaller than those of the opening Z).Said panel is revolubly connected to a pair of vertical racks z" and 2'by means of its trunnions 7L and It which are fitted in open ings in theupper ends thereof. To impart the requisite vertical movements to saidracks, there is provided a pair of pinions 2' and I mounted on alongitudinally arranged horizontal shaft 2' journaled in openings in thelegs a and A and rotated through the medium of a hand wheel or the like.Panel H is faced on one side with wood and on the other with metal, andis adapted to be fastened in raised position by means of suitablelatches J, j, 7' and j In order to permit the accurate positioning ofthe picker belt with respect to the machine, the leg a is provided witha movable foot K, (Figs. 3 and 5), the stem of which is slidably fittedin a groove formed in said leg and is retained in position by means of aset screw or similar device. To raise said foot, a strip 70 formed atits'upper end with a finger piece is fastened thereto. Owing to theprovision of this foot, it will be possible, when the'same is raised, tointroduce one edge of the picker belt therebeneath, and then positionthe upper stretch of said belt between the guides E and e which havebeen previously adjusted in conformity with the width of the belt. Afterthe introduction of the belt beneath said foot, the latter may then bedepressed and fastened in place, to clamp the belt in posi tion.

The table floor, at opposite sides of the opening 5 is formed with holesGwhich are so located as to lie directly beneath the rivets in thepicker belt, when said belt is in position on the table, sucharrangement enabling the cut rivets to be forced through said holes witha punch or other suitable implement.

The operation is as follows: The-panel H, with its wood face uppermost,is first raised into position in the opening I) and locked by means ofthe latches J, j, i and j', (which are pivoted to the side members ofthe table and below the fioor thereof). In this position, the upper faceof said panel will lie substantially flush with that of the table floor.The picker belt is then introduced beneath foot K and its upper stretchpassed over the table and between the previously adjusted guides E ande. The rivets lie at that time above the wooden face of the panel andmay be cut in any suitable manner, the said wooden face afiording asurface that will not turn the edges of the cutting tools, after whichthe belt is shifted by the spiked shafts D and (Z so as to bring the cutrivets directly over the holes G, whereupon they may be punched outthrough the belt and its battens, and through said holes. The brokenbatten is then removed and replaced by a new one which is placed inposition above the panel, said panel having been lowered at thecompletion of the removal of the rivets and subsequently raised with itsmetal face uppermost. The new batten is then riveted to the belt, thepanel constituting a work plate during this operation If the belt is tobe repaired at another point, it is shifted into proper position by therotation of shafts D and d and the afore-mentioned cycle of operationsagain takes place; otherwise the belt is removed from the machine.

WVhat I claim and desire to secure by Letters Patent of the UnitedStates, is:

1. In a machine of the class specified, the combination of a tableacross which the upper stretch of the belt is adapted to extend, a pairof legs for supporting said table, a base to which one of said legs isrigidly secured, and a foot connected to the other leg and adapted to beraised above said base to permit the lower stretch of the belt to beintroduced beneath it.

2. In a machine of the class specified, the combination of a tableacross which the up per stretch of the belt is adapted to extend, a pairof legs for supporting said table, a base to which one of said legs isrigidly secured, a foot connected to the other leg and adapted to beraised above said base to permit the lower stretch of the belt to beintroduced beneath it, and means for clamping said foot in adjustedposition.

3. In a machine of the class specified, the combination of a tableacross which the upper stretch of the belt is adapted to extend, a pairof spaced guides adjustably mounted on said table and arranged to engagethe opposite side edges of said stretch, a pair of legs for supportingsaid table, a base to which one of said legs is rigidly secured, and afoot connected to the other leg and adapted to be raised above said baseto permit the lower stretch of the belt to be introduced beneath it.
